Space shuttle Discovery undocked from the International Space Station at 8:52 a.m. EDT. Shuttle Pilot James P. Dutton, Jr. performed a fly around of the station, enabling his crewmates to conduct a photo survey of the complex.

Weather permitting, the deorbit burn is planned for 7:43 a.m. Monday, leading to a landing at 8:51 a.m. at Kennedy Space Center’s Shuttle Landing Facility.

The crew was notified that the Mission Management team has cleared space shuttle Discovery’s thermal protection systems for entry. The MMT did not work any other major issues.

Discovery will have five landing opportunities available on Tuesday; two in Florida and three in California. The first Kennedy Space Center opportunity would occur at about 7:33 a.m. EDT (1133 GMT) with a second chance at about 9:08 a.m. EDT (1308 GMT). The first Edwards AFB opportunity would be at about 9:00 a.m. EDT (1300 GMT), the second at about 10:36 a.m. EDT (1436 GMT) and the final opportunity at about 12:11 p.m. EDT (1611 GMT).
